Validation in deserializer (#36)

Browse source 
* Validation in Deserializer

Added validation in CDR deserialization: max buffer length is checked
when deserializing fields and strings are checked for null-terminator
(except for wstrings, which are serialized without null-terminator).

* Catch exceptions in serdata functions

In serdata functions rmw_print, rmw_to_sample and rmw_from_sample
catch exceptions so that correct return code is given when functions
are called from ddsi.

* Improve deserialisation validation

Refactored the deserialisation validation functions so that sequence
length is checked more properly and protection against overflows.
Renamed source files for exceptions so that it conforms to ros2 /
google c++ style guide.
